Using DataDirect XQuery® Execution Plans

DataDirect XQuery execution plan support is available only in Stylus Studio XML Enterprise Suite.

DataDirect XQuery generates an XQuery execution plan so that you can see how DataDirect XQuery will execute your query. For example, if your query accesses a relational data source, the plan will include the SQL statements that DataDirect XQuery will send to the database.

One of the main benefits of using this feature is that you can tune your queries for the best performance possible.
